摘    要:根据零水印概念,提出一种基于小波和混沌的多重水印零嵌入算法.该算法利用小波零树结构构造匹配矩阵,然后用其加载已由混沌空域置乱的多重二值图像水印.算法实现了多重水印的零嵌入,从根本上保证了水印的不可见性,并能够进行分级盲检测.实验表明,该方法鲁棒性较强,安全性良好,具有可靠性和可行性.

Abstract:According to zero-watermarking,a zero-embedding algorithm for multiple watermarks was proposed based on wavelet and chaos. Matching matrixes were structured with wavelet zerotree structure,and used to load multiple binary watermarks scrambled by chaotic sequences. The zero-embedding of multiple watermarks ensured the watermarks' invisibility thoroughly,and could implement a blind detection by stage. Experimental results show that the technique has stronger robustness,better security,dependability and feasibility.
Keywords:multiple watermarks  embedding algorithm  wavelet zerotree structure  chaos scrambling
